A South Dakota woman who prosecutors say had a blood-alcohol level almost nine times the legal driving limit has pleaded guilty to two drunken driving charges. Authorities said 45-year-old Marguerite Engle was arrested Dec. 1 when she was found passed out behind the wheel of a stolen delivery van along Interstate 90, with a blood alcohol level at 0.708. The legal limit in South Dakota is 0.08. Officials have said Engle's blood alcohol level likely is a record for the state.

She was arrested again in late December, with a blood alcohol level more than 3 1/2 times the legal limit.

Engle faces up to two years in jail when she is sentenced on Feb. 23. In exchange for her guilty pleas, prosecutors have agreed not to pursue other charges, including receiving stolen property and drug possession.
